CHICAGO — La Lob is back.
A first baseman who was the designated hitter, LaRoche had four hits and made his his first mound appearance since 2003 at Double-A Greenville.
"I have begged every manager I have ever played for to let me go out there and pitch," LaRoche said. "That has been on my bucket list for a long time."
LaRoche threw only the second 1-2-3 inning for Chicago, retiring Stephen Drew on a popup, John Ryan Murphy on a groundout and then striking out Brendan Ryan on an 85 mph pitch.
"I knew he was a pitcher, so we had talked about it before, if there was a possibility to go in there," White Sox manager Robin Ventura said. "He's a former pitcher. He pitched in the minor leagues, so you knew he could handle it."
LaRoche threw three lobs of 50-62 mph in the style of his father, Dave LaRoche, who made the La Lob famous during his time as a big league pitcher, from 1970-83.
"We had some side bets going on whether I could break 80 or not," LaRoche said. "It was fun. I tried to throw a little LaLob in there, one of my dad's old pitches. I have a lot more respect for him now, how he could throw it as high as he could and as slow as he could for a strike. I felt I threw that as slow as I could."
Mark Teixeira homered from both sides of the plate for the record 14th time, hitting his 10th grand slam and a two-run homer.
Teixeira had his second straight two-homer game and leads the Yankees with 28 homers and 73 RBIs.
Batting right-handed, Teixeira's slam off Carlos Rodon (4-4) put New York ahead 6-0 in a five-run second. Batting left-handed, he connected against Matt Albers for a 9-2 lead in a five-run fourth.
Teixeira, who went 3 for 4 with two walks, had been tied with Cleveland's Nick Swisher at 13 games homering from both sides, according to STATS. It was Teixeira's 41st multihomer game overall.
"It's a cool record to have," Teixeira said, "but hopefully I'll add to it."
