9:15am: The Mets announced they have selected right-hander Tommy Hunter to the roster, a move that had been previously reported as upcoming. Ruf was designated for assignment as the corresponding move. The corresponding move for Locastro was the placement of Edwin Diaz on the 60-day injured list.
7:38am: The Mets are finalizing their bench ahead of Opening Day, as Joel Sherman of the New York Post reports that the club has designated first baseman and outfielder Darin Ruf for assignment. That paves the way for non-roster invitee Tim Locastro to make the Opening Day roster.
Ruf, 37 in July, was acquired by the Mets in a deadline trade with the Giants last summer that sent JD Davis and three prospects to San Francisco. Following a stint in South Korea’s KBO, Ruf had spent the past three seasons hitting well for the Giants while bouncing between first base, the outfield corners, and the DH slot. Over that time, Ruf slashed .248/.358/.455 with 32 home runs and 28 doubles in 726 plate appearances, good for a wRC+ of 125. Upon acquiring Ruf, the Mets envisioned his career .891 OPS against left-handed pitching as the perfect complement to the lefty-swinging Daniel Vogelbach in a DH platoon.
Unfortunately for both Ruf and the Mets, however, that did not pan out down the stretch in 2022, as Ruf struggled mightily in 28 games as a Met, slashing a disastrous .152/.216/.197 (24 wRC+). With a guaranteed $3MM salary in 2023 and a $3.5MM club option for 2024 that came with a $500K buyout, the Mets kept Ruf on the 40-man roster throughout the 2022-2023 offseason in hopes he would be able to rebound this season. However, Sherman notes that Ruf received a cortisone injection in his wrist last month before struggling badly during camp, posting a .498 OPS in 35 spring plate appearances.
That was enough for the Mets to cut bait on Ruf, it seems, and they now have seven days to try and arrange a trade to reduce the amount of Ruf’s $3.5MM guaranteed money they’re on the hook for. Should no trade take place and Ruf pass through waivers successfully, Ruf can sign with any club for the prorated big league minimum, with Mets paying the remainder of the $3.5MM figure.
In Ruf’s place, outfielder Tim Locastro is set to make the Opening Day roster. The 30 year-old Locastro has a career wRC+ of just 82, 18% below that of the league average hitter, but is a capable defender at all three outfield spots, sports a solid career on-base percentage of .325, and most importantly, is one of the premiere baserunners in the sport. With 39 career steals in 43 attempts as a part-time player, Locastro’s 88% success rate on the basepaths is excellent, and his sprint speed has consistently topped the Statcast leaderboards through his career, ranging from 30.8 ft/s in 2019 to last year’s 30.1 ft/s figure.
Given Locastro’s already premiere baserunning abilities, he figures to benefit considerably from this season’s rule changes. In addition to larger bases in 2023, pickoff attempts have been limited. After two pickoff attempts, a third attempt must end in an out being recorded or else the runner will automatically advance one base. With Locastro likely to serve as a pinch runner and late-inning defensive replacement for the most part, the DH at-bats that would have gone to Ruf seem likely to instead go to Tommy Pham, who struggled to an 89 wRC+ in 144 games last season but sports a career .843 OPS against left-handed pitching.
