The Astros are off to one of the best starts in the Major Leagues, and perhaps no player has contributed more to the club's success than left-hander Dallas Keuchel.
Winner of the 2015 American League Cy Young Award, Keuchel is coming off his first complete game of the season, a 117-pitch gem in a 4-2 win over the Indians. With the victory Keuchel improved to 4-0.
The 29-year-old hurler had a bit of a down year in 2016, but has bounced back in a big way. He has completed at least seven innings in each of his five starts while recording a 1.22 ERA.

Keuchel will try to remain perfect when he takes the mound today against Jesse Hahn (1-1, 2.08 ERA) and the Athletics at Minute Maid Park, streaming live on MLB.TV. First pitch is scheduled for 2:10 p.m. ET.

Here's what else to watch for throughout the day (all times in ET):
Syndergaard ready to rock: NYM@WSH, 1:35 p.m.
Noah Syndergaard, who was scheduled to pitch Thursday, had his turn in the rotation skipped after slight right biceps discomfort. The flamethrower completed a successful bullpen session at Nationals Park on Friday and was cleared by the Mets to pitch today's series finale versus Washington, with New York going for a three-game sweep.
Syndergaard has dealt with a number of minor health issues this year, but it has not affected his performance. The right-hander is 1-1 with a 1.73 ERA in four starts with 30 strikeouts in 26 innings and has yet to issue a walk. It marks the most strikeouts to begin a season before allowing a walk by any pitcher in Mets history.
The 24-year-old attempts to retain his impeccable command after resting longer than usual in between starts when he takes the mound opposite Nationals righty Joe Ross in the National League East clash.
Sanchez returns from DL: TB@TOR, 1:07 p.m.
Aaron Sanchez, the American League leader with a 3.00 ERA in 2016, is slated to come back after a blister on his right middle finger landed him on the 10-day disabled list.
Sanchez threw a side session with neither pain nor setbacks before Friday's game against the Rays, the first time he's pitched without tape around the blister.
It is unclear how deep the young right-hander will be able to go considering he hasn't started a game in 15 days, but it will interesting to see if he can turn things around after opening 0-1 with a 4.38 ERA.
The Rays counter with ace Chris Archer, who is 2-1 with a 3.94 ERA in five starts.
Intriguing interleague finale: CHC@BOS, 8:05 p.m., ESPN
In what could be the last time we see the Cubs and Red Sox face each other for a while, righty Kyle Hendricks squares off against lefty Eduardo Rodriguez under the lights at Fenway Park.
Rodriguez took a no-hitter into the fifth inning of his last outing against the Orioles and is 2-2 with a 3.12 in four appearances (three starts).
Hendricks went 16-8 with a 2.13 ERA last season, but has not yet been able to replicate that same success. He is 2-1 with a 4.50 ERA in the early going.
