According to MLB.com's Greg Johns, Paxton grabbed at his upper left pectoral/shoulder area after a pitch in the seventh inning, which prompted the training staff to pay him a mound visit.
The Angels (59-58) moved into a tie with Seattle (59-58) in the American League West Division, each trailing Houston by 13 games. But he was not sharp in his attempt at No. 8 and could be headed to the disabled list for the second time this season. Paxton is expected to be sidelined for at least three weeks.
"Obviously it's disheartening news, no doubt", Seattle manager Scott Servais said.
Paxton is, unfortunately, no stranger to the disabled list. No doubt. It's been a insane season with all the injuries.
Both of these guys either seems to be really good or really bad, especially JC, who has allowed four or more earned runs in four of his last 10 starts. He was the AL pitcher of the month in July and had won seven straight starts heading into Thursday's outing.
Paxton said he woke up feeling pretty good on Friday and was a bit surprised by the diagnosis. He's 12-3 with a 2.78 ERA in 20 starts. "We're going to see how it responds here and get back as soon as possible". "I feel like I've had enough of those".
Albers had been working at Triple-A Gwinnett; now, he'll help bolster the depth for the Mariners, who have suffered a variety of pitching injuries of late.
Paxton has been the lone bright spot in the Mariners' rotation this season and entered Thursday's contest with a chance to become the first pitcher in team history to win eight consecutive games.
For the second night in a row, the Los Angeles Angels dealt Seattle a very tough loss with a ninth-inning rally. On the other side, the over is 3-0-1 in Nolasco's last four starts overall, is 5-1 in the Angels' last six games versus a left-handed starter, and is 5-2 in their last seven road games. "He said that's what we're dealing with, and we'll just have to treat it as we go and do the best we can with it".
