Riefenhauser was claimed off waivers by the Cubs on Friday. The 26-year-old performed well at Triple-A Durham in 2015, producing a 2.86 ERA in 34.2 innings of work. However, Riefenhauser has a career 6.30 ERA in the major leagues while tossing 20 innings between 2014 and 2015. The Cubs already have a solid bullpen in place, meaning if Riefenhauser stays with the club he will likely begin the season in the minor leagues.
Riefenhauser was designated for assignment Thursday. Riefenhauser was traded twice during the offseason, eventually landing with a Baltimore organization that sorely lacks pitching depth. Despite getting DFA'd to make room for Odrisamer Despaigne on the 40-man, the 26-year-old lefty should still have a shot to compete for one of the final bullpen spots on the Opening Day roster.
Riefenhauser was traded to the Orioles on Wednesday along with Mark Trumbo in exchange for Steve Clevenger. There were rumors that another player was headed to Baltimore with Trumbo, and it turns out that player is Riefenhauser, whom the Mariners acquired from Tampa Bay less than a month ago. While Riefenhauser struggled with the big-league team last season, he had a 2.86 ERA, 0.92 WHIP and 34:7 K:BB with Triple-A Durham. Look for the left-hander to compete for a bullpen role in spring training.
Riefenhauser was traded to the Mariners on Thursday, Bob Dutton of the Tacoma News Tribune reports. The 25-year-old Riefenhauser spent most of the 2015 campaign at Triple-A Durham, where he recorded a 2.86 ERA while allowing 25 hits across 34.2 innings of work. He was a late season call-up to the Rays, where he was stung for nine earned runs and 15 hits in 14.2 innings. He'll likely compete for a spot in Seattle's bullpen during spring training.
The Rays have recalled left-hander Matt Moore and four others from Triple-A Durham on Tuesday. Moore, who missed the first three months of the season while recovering from Tommy John surgery, made six starts for the Rays earlier this season. Moore struggled when he came off of the DL in early July. In the six starts, he allowed a total of 26 earned runs in 26 2/3 innings, leading to an 8.78 ERA. He has fared much better in five starts with Durham, going 2-1 with a 3.30 ERA in 30 innings. He also posted a 43:8 K:BB ratio, which includes a 16-strikeout outing two starts ago. In addition to Moore, the Rays also summoned Mikie Mahtook , C.J. Riefenhauser , Richie Shaffer and Kirby Yates from Triple-A.
