The Red Sox optioned Winckowski to Triple-A Worcester on Sunday.

Advice: Sean McAdam of The Springfield Republican reported after Saturday's 4-2 win over the Nationals that Winckowski was headed back to Triple-A, but the Red Sox didn't make the right-hander's demotion official until Sunday, when right-hander Brayan Bello (lat) was reinstated from the 15-day injured list in a corresponding move. Over 12 appearances (three starts) for Boston this season, Winckowski holds a 3.33 ERA, 1.56 WHIP and 19:11 K:BB across 24.1 innings. Rotowire.com 5 minutes ago

Miller (3-3) was stuck with the loss against Oakland on Saturday, allowing two runs on five hits and two walks over six innings. He struck out nine.

Advice: All of the damage against Miller came in the top of the third when the 25-year-old issued a leadoff walk to Lawrence Butler to open the frame, followed by back-to-back singles. The right-hander only allowed two hits outside of that inning and retired 10 of the final 12 batters he faced, but still got stuck with his third loss of the season due to a lack of run support. Miller has allowed two runs or fewer in six of his eight starts this season and recorded his second-highest strikeout total of the campaign Saturday with nine punchouts. Rotowire.com 12 minutes ago

Manager Bud Black said Saturday that Freeland (elbow) is "a week or 10 days away from getting on the mound," MLB.com reports.

Advice: Freeland played catch Thursday, Friday and Saturday and seems to have responded well to the workouts, but the Rockies aren't yet ready to have him advance to the next phase of his rehab program for his strained left elbow. While Freeland might join the Rockies for its upcoming road trip that begins Monday, the veteran southpaw will still be limited to playing catch and doesn't yet appear to be close to a return from the 15-day injured list. Given that he'll still need to complete a minor-league rehab assignment after he resumes throwing off a mound and facing hitters, Freeland doesn't look like he'll be an option for Colorado's rotation until around mid-June.

Estes (1-0) earned the win over the Mariners on Saturday, allowing one run on two hits over five innings while striking out five.

Advice: Estes was efficient throughout his five innings of work, doing much of the damage with his slider and four-seamer. While he only threw eight of his 17 first pitches for strikes, the right-hander was frequently able to work his way back from being down in the count and gave up only two hits on the night, though one of those was a home run. Estes also took a liner off his right bicep in the first, but still managed to scoop it up and retire Julio Rodriguez for the out at first base before waving off the trainer and continuing on with the inning. It was certainly an impressive debut for the promising rookie, though it remains to be seen whether or not he'll stick around in the rotation for another start. Rotowire.com 25 minutes ago

Blach is slated to start Sunday's game against the Rangers at Coors Field.

Advice: Blach will pick up his second start of the season as he joins the rotation as a replacement for Peter Lambert, who was recently moved to the bullpen. The veteran southpaw had worked in relief in both of his past two appearances for Colorado, but because he handled four- and three-inning workloads in those outings, he should be reasonably stretched out as he re-enters the rotation.
