Casilla, 30, has not seen big league time this year and played in just one game last year for the Orioles. Before that, however, he was rather an active utility player, mostly from the Twins. All told, Casilla has taken 1,893 plate appearances and produced a .247/.302/.331 slash with 80 stolen bases. He has spent most of his time at second, but also has plenty of experience playing shortstop.

Though he’s yet to receive a call-up, Casilla has actually been quite productive this year at Triple-A. Over 142 plate appearances, he has slashed .315/.379/.449. Though a .363 BABIP has helped drive that productivity, Casilla is showing better patience and power numbers than he did last year in the upper minors.

Casilla, 30, only appeared in one Major League game in 2014 (with the Orioles) as he spent most of the season at Baltimore’s Triple-A affiliate.  Since first breaking into the bigs in 2006, Casilla has posted a .247/.302/.331 slash line and gone 80-for-91 in stolen base chances over 1893 career plate appearances with the Twins and Orioles.

The 30-year-old has previously spent time with the Twins and Orioles, averaging 269 trips to bat over the 2007-13 time frame while slashing .248/.302/.332 and swiping 80 bags in that stretch. Last year, however, Casilla only got one game in the bigs, spending most of the year at Triple-A with Baltimore.

The former Twin and Oriole has appeared in parts of nine seasons. He played just one game with Baltimore last season and spent most of his season at the Triple-A level. While neither a defensive wizard nor offensive threat, Casilla has occasionally approached a league average rate of performance. He’s a career .247/.302/.331 hitter in 1,893 plate appearances.

Casilla has experience at second base, shortstop, and third base with most of his time spent at the keystone. Under Joe Maddon, the Rays were known for valuing flexibility. It stands to reason that the club still prefers players with plenty of utility.

Guilmet, 27, pitched 10 1/3 innings for the Orioles this year, striking out 12 batters and walking just two but giving up two homers and six earned runs. Guilmet, a long-time closer in the Indians’ system, has always posted strong numbers in the minor leagues, but hasn’t gotten a clean shot at a big-league job, perhaps in part because of his underwhelming stuff — most of his fastballs don’t top 90MPH, and he doesn’t get many ground balls.

Casilla tells Eduardo A. Encina of the Baltimore Sun (via Twitter) that he thought his season was over, and that he had been getting ready to play winter ball in the Dominican. The 30-year-old Casilla hit .264/.315/.320 in 213 plate appearances for Triple-A Norfolk this year. He has not played since August 30 due to a hamstring injury. He is in the Orioles’ lineup today, playing third base.

• The recent re-signing of Alexi Casilla to a minor-league deal gives the Orioles another backup plan if Manny Machado is unable to completely recover from his knee injury by the beginning of the season, Eduardo A. Encina of the Baltimore Sun writes. If Machado isn't ready to go, the Orioles could move Ryan Flaherty to third and start either Casilla or Jemile Weeks at second. Jonathan Schoop might also be a possibility there, but Encina notes that the O's would like to give Schoop more time at Triple-A.
• The Marlins are unlikely to re-sign outfielder Chris Coghlan, says MLB.com's Joe Frisaro. They non-tendered him last month, and have since added Brian Bogusevic, who looks likely to occupy an outfield bench role. The Marlins could have a starting outfield of Christian Yelich, Marcell Ozuna and Giancarlo Stanton.
• Adam Lind is glad the Blue Jays exercised his $7MM option this offseason, Shi Davidi of SportsNet.ca reports. "I was really hoping I was going to be back, but for some reason you never find out until the last minute, and I’m really excited and pumped to be able to stay here for another season," Lind says. There have also been trade rumors about Lind this offseason, but Davidi writes that the Blue Jays never really wanted to trade him. 

Casilla, who can play shortstop, second base and third base, could be a candidate for a bench job in Baltimore in 2014. He has a lifetime .248/.302/.332 line in parts of eight seasons, seven of them with the Twins.

The 29-year-old switch-hitter batted just .214/.268/.295 in 62 games (125 plate appearances) in his only season with the Orioles. Baltimore claimed Casilla off waivers from the Twins last offseason and avoided arbitration with him by agreeing to a one-year, $1.7MM contract with a $3MM club option ($200K buyout) for the 2014 campaign.

Casilla has turned himself into a solid defender at second base over the past several seasons and can handle shortstop as well, but his complete lack of offense — he batted just .234/.278/.314 in 451 plate appearances from 2012-13 — likely limits him to a minor league deal this offseason.

• Steve Melewski of MASNsports.com examines potential free agent starting pitching targets for the Orioles, whose starters combined for a 4.57 ERA in 2013. The article profiles Matt Garza, Hiroki Kuroda, Santana, Dan Haren and Ricky Nolasco, noting that the O's have been connected with Nolasco in the past.
• In a separate article, manager Buck Showalter tells Melewski that the front office will indeed consider adding a free agent arm this offseason. However, Showalter says the team is also excited about young pitchers such as Eduardo Rodriguez, who finished up the year at Double-A. The manager added that while he's never been turned down by owner Peter Angelos when proposing a deal, he's "not a guy that asks a lot."
• Showalter sounds as though he expects Brian Roberts to return next season, Melewski writes. The oft-injured second baseman has appeared in just 133 games over the last three seasons, but we'd heard previously that he's among the free agents whom the club is most interested in retaining.
• In an article reporting on the O's decision to decline their $5MM 2014 option on Tsuyoshi Wada, which was announced earlier this evening, Roch Kubatko of MASNsports.com discloses that the team will announce next week that it has also declined its $3MM option on Alexi Casilla. The infielder is in line for a $200K buyout if that does come to pass.

Casilla had been a non-tender candidate in Minnesota since he projects to earn $1.8MM following a disappointing season. The 28-year-old hit .241/.282/.321 in 326 plate appearances in 2012. Orioles executive VP Dan Duquette said the acquisition of Casilla means the Orioles won't pursue other second basemen, Connolly reports.

• Rays starter James Shields could become a target for the Twins in Wolfson’s view.
• Assistant GM Rob Antony was expected to speak with the agent for second baseman Alexi Casilla yesterday. It seems likely that the Twins will non-tender Casilla, who’s arbitration eligible this winter. You can view MLBTR’s full list of non-tender candidates here.
• The Twins have inquired about right-hander Randy Messenger. The 31-year-old last pitched at the MLB level in 2009, but he is coming off of a strong season with the Hanshin Tigers in Japan. Messenger posted a 2.52 ERA with 7.6 K/9 and 3.0 BB/9 in 196 2/3 innings this past season.

Alexi Casilla, the Twins’ starting second baseman, isn’t hitting at all this year and his poor offensive production could cost him his job this coming offseason. The switch-hitter has a .223/.259/.293 batting line in 234 plate appearances so far in 2012. Though 13 of his 14 stolen base attempts have been successful, he’s not providing value on offense. 

Casilla is a decent defensive middle infielder best-suited for second base, according to a pre-season scouting report in The Fielding Bible: Volume III. The 28-year-old Proformance client has spent most of this season at second base, making a few appearances at third base and none at shortstop. 

Unless the Twins believe Casilla’s defense makes up for his below-average bat, they’ll have to consider non-tendering him this offseason. He’s earning 1.38MM this year as a second-time arbitration eligible player and would be in line for a salary approaching $2MM if Minnesota tenders him a contract this offseason — MLBTR contributor Matt Swartz projects a salary of $1.8MM.

That may be more than the Twins are willing to commit to a player who isn’t hitting, especially since they have internal alternatives up the middle. Brian Dozier and Jamey Carroll will be back in 2013. And pre-arbitration eligible utility player Eduardo Escobar, who joined the Twins in the Francisco Liriano trade, provides Minnesota with another affordable infield option. Many more utility infield options will be available on minor league deals in a matter of months.

Casilla has added some value according to the versions of the wins above replacement metric at Baseball-Reference (0.9 WAR) and FanGraphs (0.4 WAR). But it’s hard to see Twins general manager Terry Ryan committing a roster spot and a couple million dollars to a player who contributes so little on offense. Instead, it looks as though Casilla will hit free agency a year early barring a late-season surge.

As MLBTR's arbitration tracker shows, the Twins are now finished with their arbitration eligible players.  They committed a total of $8.432MM to Casilla, Francisco Liriano, and Glen Perkins for 2012.

Two arbitration eligible players remain unsigned overall: Garrett Jones and Casey McGehee of the Pirates.
