Antonio Senzatela makes his big-league debut in the Rockies season-opening series finale at Milwaukee Thursday afternoon. While Senzatela had a 4.61 ERA during the spring he caught the attention of the Rockies and scouts from other teams with not only his velocity but his ability to pitch, moving the ball up and down, and in and out to hitters.

The numbers that stick out from his 27 1/3 innings over five spring appearances were three walks and 27 strikeouts.

Senzatela was ranked the 10th best prospect in the Rockies system prior to this season by Baseball America. He is 41-19 with a 2.45 ERA in 88 minor league starts.

Shoulder problems that did not require surgery led to him spending two lengthy stints on the disabled list at Double-A last year, but he was 4-1 with a 1.82 ERA in seven starts, striking out 27 and walking nine in 35 innings.

LHP KYLE FREELAND, ranked the 8th best prospect in the organization by Baseball America, makes his big-league debut in Friday’s home opener against the Dodgers.

The Rockies are looking for the rookies to turn around an early struggle for the Rockies rotation. While the Rockies won two of their first three games in Milwaukee starters Jon Gray, Tyler Anderson and Tyler Chatwood combined for an 8.04 ERA. It’s the highest ERA in the NL, and 28th among the 30 Major League teams.

The Yankees (8.74) and White Sox (10.13) have the two worst ERAs in the AL.

LHP CHRIS RUSIN, on the disabled list because of a right oblique injury, will make a rehab assignment appearanceĀ in Triple-A Albuquerque’s season-opener against Salt Lake City tonight. He is scheduled to work three innings or throw 45 pitches.

Rusin arrived at spring training in contention for a spot in either the rotation or bullpen. Now the Rockies are looking at him as a reliever while he rebuilds the shoulder strength.

TWO FORMER BREWERS, Mark Reynolds and Gerardo Parra, have enjoyed the season’s first three games at Miller Park. They are both hitting .545, tops in the NL among players with at least 10 at-bats.

Reynolds has five RBI, tied with Joc Pederson of the Dodgers and Travis Shaw of the Brewers for the NL lead. Parra is one back with four RBI.

THE ROCKIES are among six NL teams without an error. The other five teams are the Braves, Cardinals, Phillies, Marlins and Nationals. There are four AL teams which have not committed an error _ the Orioles, Royals, Twins and As.

 

Mark Reynolds is having a more enjoyable time at Miller Park in the opening three games of this season than he had in his previous games, including 2014 when he was with the Brewers and hit .196.

Reynolds has hit in each of his first three games in a season for the first time, and also has driven in at least one run in each of the first three games. Reynolds is hitting .545 with five RBI, three doubles and a home run.

Only two other times did he even have a hit in the first game of the season (2007, 2010), much less than first three games.

With the first three games of this season, Reynolds has raised his career average at Miller Park to .202.

TYLER CHATWOOD gave up four earned runs in six innings in his 2017 debut, a 6-1 loss at Milwaukee on Wednesday. That equaled the most runs he allowed in a start last year. He gave up four at Philadelphia on Aug. 14 last year.

The only other time he allowed more than two earned runs in a road start last season was June 18 when Miami scored three runs against him.

Chatwood was 8-1 with a 1.69 road ERA last year, the 12th lowest road ERA for a pitcher with at least 80 innings since 1969.

JORDAN LYLES worked the final three innings in Wednesday’s loss, giving up two runs. Those were the first runs allowed by a Rockies reliever this season. The bullpen combined to work 8 1/3 scoreless innings in the first two games at Milwaukee, both victories.

THE ROCKIES are traditionally challenged on the road. They have won two of three from the Brewers to open the season and close out the season-opening series with a day game on Thursday.

The Rockies have had a winning record on the road only once in their first 24 years — 41-40 in 2009 on their way to claiming the NL wild-card and their third post-season appearance.

ANTONIO SENZATELA is one of nine members of the Rockies 25-man roster who was on an Opening Days 25-man roster for the first time this season.

Fellow starters Tyler Anderson, Jon Gray and Kyle Freeland were on the roster for the first time along with Stephen Cardullo, Dustin Gorneau, German Marquez and Scott Oberg. Chatwood is the only member of the rotation who had been on an Opening Day roster previously.
