The status of the Cubs’ pitching staff took a few twists Thursday.
The remainder of Tyler Chatwood’s season remains uncertain after he was placed on the 10-day disabled list because of left hip inflammation, retroactive to Monday. Manager Joe Maddon said the discomfort nagged Chatwood earlier this season and became more acute Saturday, when he walked three batters in two-plus innings at Pittsburgh.
The rest of Chatwood’s season seems clouded because of his injury and struggles. He was dispatched to the bullpen earlier this month after the arrival of Cole Hamels in a trade from the Rangers. Chatwood has walked 93 batters in 101 2/3 innings and failed to pitch deep in many of his 20 starts.
Alec Mills was promoted from Triple-A Iowa to start Friday’s game against the Reds. Maddon said the front office made the decision to start Mills, 26, who is 5-12 with a 4.84 ERA in 23 starts but allowed only three hits in six innings Saturday against Oklahoma City.
Mills pitched two scoreless innings in relief for the Cubs against the Cardinals on July 27. The right-hander also appeared in three games for the Royals in 2016, allowing five earned runs in 3 1/3 innings.
The Cubs will make a corresponding move before Friday’s game.
Reliever Dillon Maples also was recalled from Iowa, where the 26-year-old has a 2.41 ERA with nine saves and 71 strikeouts in 37 1/3 innings while limiting opponents to a .147 batting average.
Maples has allowed one earned run in his last 23 2/3 innings (0.38 ERA) while striking out 49. He has allowed five earned runs in 3 1/3 innings in three stints with the Cubs this season.
Left-hander Mike Montgomery believes he could rejoin the rotation by the end of next week. Montgomery said his left shoulder felt great after playing catch Thursday, and he plans to throw a bullpen session Sunday.
Reliever Brian Duensing (left shoulder inflammation) left for Omaha to start a minor-league rehab assignment with Iowa.
