Andrew Miller broke the Major League record for strikeouts by a relief pitcher in one postseason with 29 on Saturday night.

Miller struck out two batters in two innings as the Cleveland Indians won Game 4 of the World Series to take a 3-1 lead over the Chicago Cubs.

The left-hander has pitched 17 innings in his nine appearances this postseason.

Miller finally gave up his first run of the playoffs Saturday, bringing his postseason ERA to 0.53.

Andrew Miller made history in Game 3 of the World Series on Friday night, extending his scoreless innings streak to 15 this month.

Miller surpassed Rich Gossage (14 1/3 scoreless innings in 1981) and Mariano Rivera (14 each in 2003 and 2009) in the record books.

He has 27 strikeouts in these playoffs, the second most single postseason by a reliever only to Francisco Rodriguez's 28 with Anaheim in 2002.

Corey Kluber made World Series history on Tuesday night by striking out eight batters through the first three innings.

Kluber tossed six shutout innings as the Cleveland Indians took Game 1 of the World Series 6-0 over the Chicago Cubs.

Bob Gibson, Randy Johnson and Orlando Hernandez had each struck out seven among their first nine outs.

After we saw a jump in home runs during the regular season, the spike has carried over into the playoffs.

Heading into play on Tuesday, 108 runs had been scored in the postseason and half of them were as a result of home runs, the highest percentage since the wild card was introduced.

The Chicago Cubs became just the second team in Major League history to have two pitchers hit home runs in the same postseason series when Jake Arrieta took Madison Bumgarner deep in the second inning on Monday night.

Travis Wood hit a home run in Game 2 of the NLDS.

It's the first time since the 1924 Giants that two pitchers from the same team have gone deep in a playoff series.

"It was probably the best pitch I threw to (Arrieta) in the at-bat," Bumgarner said. "I was thinking about going to the breaking ball, but the way it looked to me, I didn't see any need to. Sometimes you feel like you can help a guy out by slowing it down. But from what I saw, I felt like I was making the right pitch. He just made a good adjustment."

The San Francisco Giants beat the Cubs 6-5 in 13 innings to extend the series to at least four games.
