Both came close to no-hitting the Astros. Here's a closer look at this marquee matchup at Rangers Ballpark in Arlington:

Awesome April: Verlander had the best April of his career in posting a 1.83 ERA. That's more than a half run better than last season (2.41), which was his previous career best for the month. He also had 41 strikeouts in 39 1/3 innings, also his career high for the opening month. It's a little bit of a change for Verlander, who is 14-17 in 41 April starts during his career.

Darvish has had nine of his 22 career wins come in April, including a 5-1 mark this season. He had a 2.33 ERA and 58 strikeouts for the opening month, and came within an out of throwing a perfect game against Houston. He allowed only 23 hits in 38 2/3 innings.

Keeping it going: Verlander has won more games in May (25) than any other month during his career, and his 2.69 ERA probably has a lot to do with it. It's also been his best strikeout month with 264 -- 37 more than he's had in April.

Darvish's ERA has risen to 3.83 for this month, and he's given up the long ball, allowing four home runs after giving up just one in April. He's fallen behind early in starts against Boston and Houston, but he got stronger as those games went along and his offense rallied for a win and a no-decision.
