Dodgers Notes: Rosario, Betts, Freeman, Yamamoto

For the second time in as many years, the Dodgers have acquired Amed Rosario ahead of the trade deadline. Coming off a down season in Cleveland last year that left him as a below-average hitter overall, Rosario was used almost exclusively against left-handed pitching during his time with L.A. last season. Despite the fact that he’s hit both righties and lefties quite well with the Rays this year, however, manager Dave Roberts told reporters (including Bill Plunkett of the Orange County Register) that Rosario’s role with the club will be similar to last year.

“Honestly, to be quite frank, he’s not on this team, and we didn’t acquire him, to be an everyday player — he didn’t play every day in Tampa — and to hit righties,” Roberts said (as relayed by Plunkett) when asked about Rosario’s role this year.

Rosario has improved considerably in terms of both his overall slash line, which sits at .308/.332/.421 (116 wRC+) in 277 trips to the plate, and in boosting his slash against righties to a respectable .299/.324/.395 (107 wRC+). Even so, it’s worth noting that the 28-year-old is still hitting lefties better than same-handed pitching. With lefty-swinging Gavin Lux at second base, Shohei Ohtani locked into everyday at-bats at DH, and a trio of lefty-swingers in James Outman, Jason Heyward, and Kevin Kiermaier all part of the club’s deep outfield mix, it’s fair to wonder where exactly Rosario would fit into the club’s lineup against right-handed pitching.

Rosario has plenty of experience at shortstop and played a bit of third base for Tampa this year, but the club seems satisfied with Kiké Hernández at third base and Nick Ahmed at shortstop for the time being. Perhaps more importantly, each of those pieces are only stopgap options to begin with. Plunkett goes on to note that Roberts indicated the club hopes to see superstar Mookie Betts return to the lineup on August 12 or 13. Betts has been sidelined since mid-June after an errant pitch fractured his left hand.

Betts was in the midst of a MVP-caliber season prior to his injury, slashing an incredible .304/.405/.488 in 72 games that’s made all the more impressive by the fact that he was simultaneously making a relatively seamless transition to becoming the everyday shortstop in L.A. this season. While it seemed at one point that veteran shortstop Miguel Rojas had staked his claim to regular starts at short in Betts’ absence, a forearm issue sent him to the shelf as well and seemingly leaves the position for Betts to slide back into upon his return.

While third base figures to be an option for a while longer with Max Muncy still out due to a strained oblique, Freddie Freeman’s impending return from the restricted list could lessen opportunities for Rosario at the hot corner as well. Freeman has been out for about a week now as he tends to his family following the hospitalization of his son, Maximus, due to Guillain-Barré syndrome but Roberts notes that he could return to the club as soon as this week when they face the Phillies in a three-game set that starts on Monday. Freeman’s return to action would free up Cavan Biggio from regular reps at first base, giving the club a left-handed infield option with plenty of experience at third base the club may prefer to utilize over Rosario against right-handers.

Sticking with news regarding currently-unavailable stars, Plunkett notes that right-hander Yoshinobu Yamamoto threw a 20-pitch bullpen session today in his first time taking the mound since being sidelined with a strained rotator cuff back in June. Roberts told reporters (including Plunkett) that the bullpen was a “big step forward” and that Yamamoto is slated to throw another bullpen on Tuesday as the club angles for a return to action for the righty sometime next month. The right-hander received the biggest pitching contract in MLB history before throwing a single pitch in the big leagues this past winter and immediately made good on it with a 2.92 ERA and 2.68 FIP in 14 starts for the Dodgers before being shelved due to the injury. Injuries to Yamamoto and Walker Buehler led the club to fortify their rotation at the deadline by adding right-hander Jack Flaherty, but it seems possible that Yamamoto and Flaherty could join forces down the stretch and into the postseason at the front of L.A.’s rotation alongside Tyler Glasnow.
