From April 2 through April 24, Lincecum won his first four decisions of the 2008 season. On May 15, Lincecum struck out 10 Astros in six innings. Houston first baseman Lance Berkman offered his view of Lincecum: "He has three almost unhittable pitches...When he throws those off-speed pitches where he wants, you've got no chance." After his team fell to Lincecum and the Giants 6–3 on May 27, Diamondbacks first baseman Conor Jackson gave his impression of facing Lincecum: "From what I saw tonight, that's the best arm I've seen all year, no doubt. You've got to almost hit a ball right down the middle. You're going to pop up the ball at your bellybutton, which we all did tonight, and the one down, it's coming in at , you're not going to put too much good wood on it. Even the ones down the middle are coming at 98. He's good, man."
