2nd Update: Bettis Returns to Rehab; Oh Joins Rockies

The Rockies continue to juggle their roster, looking to get their rotation and bullpen back in order.

-- Chad Bettis, on the disabled list with a blister problem on his right middle finger, will resume his rehab assignment with Triple-A Albuquerque, making his second start for the Isotopes in Saturday's game at Colorado Springs. It will be Bettis' first appearance since he came out of a start for the Isotopes after four innings last Saturday because the blister flared up.

Bettis will not be on a pitch count. The hope is he can throw at least 70 pitches without a problem, which would put him in position to return to the active roster before too long.

-- DJ LeMahieu, on the disabled list since July 21 with a left oblique strain, had his attempt to take swings in the indoor cage put on hold for a second day in a row on Saturday, but he could get the opportunity Sunday. He did play take ground balls on Friday, and played catch on Saturday, which was the first time he has thrown since the injury. LeMahieu is hoping he can return to the active roster when he is eligible to be activated Tuesday.

-- New bullpen addition Seunghwan Ohjoined the rockies on Saturday. The Rockies acquired Oh from the Blue Jays in exchange for minor-league prospects Chad Spanberger, a first baseman, and Forrest Wall, a converted outfielder.

He made a strong first impression, going 6-3 with a 1.92 ERA with the Cardinals in 76 relief appearances in 2016, but was 1-6 with a 4.10 ERA a year ago. With the Blue Jays this year he has a 2.68 ERA in 47 innings, striking out 55 with only 10 walks.

With the Jays, Oh struck out 55 with 10 walks, and was tied for fifth in the AL in 48 appearances. His 5.5 strikeout-to-walk ratio was 10th among AL relievers. He is unscored upon in 19 of 21 appearances dating back to June 7, having allowed two runs in 20 innings.

-- Left-hander Sam Howard was optioned back to Albuquerque to make room for Oh. Howard, in his second stint with the Rockies this season, was called up July 14 when Jon Gray was sent to Triple-A, but Howard had not pitched in the two weeks after that call up. He did make his major league debut with a scoreless innings against the Diamondbacks on June 10 during an early call up. He was with the Rockies from June 9-13 that time.

--Outfielder Raimel Tapia was sent back to Triple-A Albuquerque to make room on the 25-man roster for German Marquez, scheduled to start on Sunday, to come off the disabled list. Tapia was called up on June 30, and was 4-for-18 with a home run, two doubles and five RBI in 14 games.

--Marquez had been on paternity leave, and had to be reactivated Friday. A paternity covers three games, and Marquez, who flew home to Venezuela last Sunday, was able to extend it to five days before the Rockies were off Monday and Thursday. Marquez is 8-8 with a 5.00 ERA in 20 starts this season.

--Outfielder David Dahl was activated from the 10-day disabled list and optioned to Triple-A Albuquerque. Dahl suffered a broken bone in his right foot June 1. He appeared in seven games on a rehab assignment with Albuquerque, and hit .280 with a double, home run and RBI. After opening the season at Albuquerque, Dahl was recalled on April 22, and hit .275 with eight runs scored, three doubles, two triples, four home runs before fouling the ball off his foot and suffering the broken bone.

-- Left-handed reliever Mike Dunn was transferred from the 10-man disabled list to the 60-day disabled list, which opened a spot on the 40-man roster for Oh. Dunn was placed on the disabled list July 7 with an inflamed AC joint. He was a 9.00 ERA in 25 appearances with the Rockies before being disabled, allowing 17 earned runs and 18 walks in 17 innings.
