The Braves announced that they’ve placed right-hander Julio Teheran on the 10-day disabled list due to a right thumb contusion and selected the contract of righty Luke Jackson to take his spot on the 25-man roster. Atlanta had an open spot on the 40-man, so the team didn’t need to make a corresponding move in that regard.
Teheran, still just 27 years of age, is sporting a respectable 4.31 ERA on the season, though there’s plenty of reason to believe that he’s been fairly fortunate to maintain that mark. The right-hander’s average fastball velocity is down to a career-worst 89.3 mph, and he’s averaging a career-high 4.18 walks and 1.77 homers per nine innings pitched. Beyond that, Teheran’s chase rate and swinging-strike rate are down from his career levels, and he’s benefiting from a .225 BABIP and an 80.4 percent strand rate. Fielding-independent metrics like FIP, xFIP and SIERA all peg Teheran around 5.00 or higher.

It’s not clear how long Teheran will miss, though there’s no indication that he’s expected to be out for a prolonged period. With off-days on June 7 and 11, the Braves can skip the fifth spot in their rotation and stick with current starters Sean Newcomb, Mike Foltynewicz, Brandon McCarthy and Anibal Sanchez. If they have to dip into their Triple-A ranks, Matt Wisler has already made three spot starts this season and could be the first line of defense to do so again. Max Fried and Lucas Sims are also starting in Triple-A and are on the 40-man roster, though they’ve been used primarily out of the ’pen in the Majors so far in 2018.
As for Jackson, this’ll be the third time he’s been selected to the team’s 40-man roster this season. Atlanta has already outrighted Jackson on two occasions, but he’s stuck with the organization and will now embark on his third stint with the Major League team in 2018. The 26-year-old has surrendered two runs in 1 1/3 innings at the MLB level so far and posted a 4.62 ERA in 50 2/3 innings for the Braves last year. In 21 1/3 Triple-A frames so far in 2018, he’s pitched to a pristine 1.69 ERA with 34 strikeouts against 10 walks.
