The 26-year-old is scheduled to undergo an MRI to find out the severity of the injury, as this throws a wrench in him finding consistency this season. He has given up four or more runs in eight of his 15 starts. He entered the season with a career ERA of 2.93, but has a record of 5-4 with a 4.55 ERA, and got the no decision on Saturday despite an 8-7 win for his team. A bit of good news for the Mets is that they did activate Robinson Cano from the IL, but saw starter Jason Vargas leave Sunday's start against the Cardinals with a cramp in his left calf.
Elsewhere, one bad outing on Friday was the tipping point for the Los Angeles Angels, who have designated reliever Cody Allen for assignment. The move was announced on Saturday, just one day after Allen gave up four runs in just 2/3 of an inning at Tropicana Field in a 9-4 loss to the Tampa Bay Rays. The former Cleveland Indians All-Sar has an ERA of 6.26 over 23 innings and 25 appearances in his first and only season with the Angels. The 30-year-old did have a stretch of five straight seasons with an ERA under three, which ended last year, when he posted a 4.70 ERA in his final year with the Indians. That could've been the beginning of the downfall of his career, but maybe his next stop will be the fresh start that he desperately needs.
