Zimmermann underwent successful core muscle repair surgery Thursday. This comes as a bit of a surprise, as there had been no mention of any injury prior to the procedure. Dr. William Meyers performed the surgery in Philadelphia, noting afterwards that Zimmermann should be ready for spring training. The veteran right-hander turned in a 4.52 ERA, 1.26 WHIP and 111:26 K:BB across 25 starts (131.1 innings) for the Tigers in 2018.
Zimmermann didn't factor into the decision in Friday's 6-5 loss to the Brewers, giving up five runs on eight hits and two walks over four innings while striking out four. It was a rough end to the season for the right-hander, but at least he avoided taking his ninth loss. Zimmermann made 25 starts in an injury-plagued campaign, posting a 4.52 ERA, 1.26 WHIP and 111:26 K:BB in 131.1 innings, but unless the front office can find a taker for his contract, he should head into 2019 with a spot in the Detroit rotation waiting for him.
Zimmermann did not factor into the decision Saturday despite allowing only two runs in seven innings against the Royals. He gave up three hits (including a home run) and two walks while striking out five. Th righty threw 93 pitches (58 strikes) and was in line for the win before Joe Jimenez blew that opportunity in the eighth and stole the victory for himself when Detroit later rallied. Zimmermann's gem marked his longest outing since he pitched eight frames July 6. He owns a 4.31 ERA and has struck out only 7.6 batters per nine innings but has walked only 1.7 per nine in 127.1 innings this year. He'll have a mere hint of mixed-league streamer appeal in his scheduled start against the tough Brewers offense Friday.
Zimmermann (7-8) allowed five runs on seven hits and two walks over 3.2 innings to take the loss Monday against the Twins. He struck out two. Zimmermann limited Minnesota to a single run through three innings but struggled in the fourth. The veteran allowed a leadoff double and five singles in the frame before getting the hook with two outs and his team down 5-0. Zimmermann continues to be an up-and-down fantasy option, and he'll carry a mediocre 4.41 ERA into his next start Saturday against the Royals.
Zimmermann (7-7) took the loss against the Astros on Tuesday, allowing five runs (four earned) and six hits over five innings. He struck out three and walked one. Zimmermann allowed all five runs via the home run, as he induced only two groundballs for the game. The 32-year-old has a 4.17 ERA and 1.22 WHIP across 116.2 innings heading into his next start against the Twins on Monday.
