21 Tyler Chatwood SP

Chatwood (hip) was activated from the 10-day disabled list Monday, Mark Gonzales of the Chicago Tribune reports.

Chatwood is back with the big club after spending close to two weeks on the shelf with a hip injury. The right-hander struggled to a 5.22 ERA and 85:93 K:BB across 101.2 innings with the Cubs prior to landing on the shelf, and he didn't fare much better in a pair of minor-league rehab starts, allowing seven runs across 6.2 innings while walking 10 and striking out four. He figures to settle into a long-relief role down the stretch.

Chatwood (hip) tossed 4.1 innings and gave up two runs on three hits and five walks while striking out three during a 77-pitch rehab start Monday for Triple-A Iowa.

Chatwood's pitch count suggests he's ready to handle a starter's workload with the big club, but he's unlikely to get that opportunity with his control still representing a major concern. The right-hander maintains a 8.2 BB/9 for the season -- far and away the worst mark in the majors among any pitcher who has covered at least 100 innings -- and threw only 50.6 percent of his pitches for strikes Monday, providing little hope that his walk issues are behind him. It wouldn't be surprising if the Cubs gave him more time in the minors to work through his control problems, but if Chatwood is activated from the disabled list when rosters expand Saturday, expect him to move to the bullpen and serve in a low-leverage role.

Chatwood (4-6) took the loss Saturday as the Cubs fell 3-1 to the Pirates, giving up three runs on two hits and three walks over two innings without striking out a batter.

Making his first start since July, Chatwood once again couldn't find the plate with any consistency, the same issue that cost him his rotation spot in the first place. Expect him to move back into a long-relief role once Mike Montgomery (shoulder) is ready to return to action, if not sooner.

Chatwood will return to the rotation for a spot start Saturday in Pittsburgh, Carrie Muskat of MLB.com reports.

Chatwood pitched himself out of the rotation in late July after walking 85 batters in 94 innings. he hasn't looked any better in three relief outings, walking five in 5.2 innings and posting a 6.35 ERA. He'll be called on to fill in for Mike Montgomery, who hit the disabled list with shoulder inflammation Friday.

Chatwood will head to the bullpen after the Cubs acquired Cole Hamels from the Rangers on Friday, Carrie Muskat of MLB.com reports.

Chatwood has struggled through 19 starts this season, accruing a 4.98 ERA and 1.78 WHIP with an 82:85 K:BB over 94 innings. The Cubs will hope to get him back on track by using him out of the bullpen, as he's had control issues all year. Chatwood issued six walks in each of his previous two starts.
