Keuchel aiming to add to MLB-best win streak

All eyes will be on Astros starter Dallas Keuchel as he takes the mound Tuesday. The American League Pitcher of the Month for April has a 6-0 record, the longest active streak in the Majors without a loss to start the season.

With a 1.69 ERA, Keuchel has scattered just 37 hits and issued 14 walks for a 0.87 WHIP. He's struck out 50 batters over 58 2/3 innings this season. According to Statcast, when Keuchel has gotten a swinging strike this season, it's been on a pitch out of the strike zone an MLB-leading 71.1 percent of the time. Among swinging third strikes, an MLB-leading 81.6 percent have been outside the zone.

Tom Koehler will oppose him for the Marlins. The right-hander has a 5.60 ERA in seven starts, and has made it through six innings just twice this season. Still, with his eighth start, Koehler will tie Dan Straily for the club lead, and he enters the game second on the staff in innings pitched (35 1/3) this season.

Three things to know about this game
• Evan Gattis has the most experience of any Astros player facing Koehler over the past five seasons. Houston's catcher/designated hitter is hitting .455 (5-for-11) against Koehler with 2 RBIs.

• Keuchel has not allowed an earned run in his career against the Marlins, but has not beaten them, either. In his lone appearance against Miami, Keuchel went seven innings in a 2014 start, giving up two runs -- both unearned -- and was tagged with the loss despite seven strikeouts over seven innings.

• Koehler has faced the Astros just once before as well, earning a win in a 2014 start during which he went five innings and allowed three runs on nine hits. He struck out two and did not walk a batter.
