HILTON HEAD ISLAND, S.C. -- K.J. Choi's early tee time and quick start moved him to the top of the rain-delayed RBC Heritage on Friday.
Choi shot a 67 to get to 5-under 137, one stroke ahead of Robert Allenby and two in front of a group led by former world No. 1 Luke Donald as the second round was suspended because of heavy storms. Allenby was among 65 players still on the course when the rain hit Harbour Town Golf Links. Officials delayed the round shortly before 3 p.m. and then sent everyone home until Saturday morning after waiting through about 90 minutes of steady, heavy rain.
Allenby has 13 holes to finish when play resumes Saturday morning.
Donald shot a 69 and joined Billy Hurley III (69) and first-round tri-leader Scott Langley (73) in the clubhouse two shots behind Choi. Bo Van Pelt and Ben Martin were also at 3 under early in their rounds.
Masters contenders Matt Kuchar and 20-year-old Jordan Spieth faltered after their strong starts at Harbour Town.
Kuchar, who tied for fifth last week at the year's first major, had a pair of double bogeys on his first six holes before the rains came and stood four shots behind Choi.
Spieth, a Masters rookie who tied for second at Augusta National, had a 74 and was at 1-over 143 -- good enough to make the projected cut of 4 over, but well off his opening 69.
Chapman cleared: Cincinnati Reds closer Aroldis Chapman has been cleared to throw batting practice for the first time since he was hit in the face by a line drive during an exhibition game on March 10.
Chapman sustained fractures of his nose and and a bone above his left eye when hit by the drive off the bat of Kansas City's Salvador Perez.
Reds manager Bryan Price said Friday he wasn't sure exactly when Chapman will throw but said it likely will be during the team's 10-game trip that ends April 27.
Tigers make moves: The Detroit Tigers have recalled right-hander Justin Miller from Triple-A Toledo and optioned outfielder Tyler Collins to Toledo. The team announced the moves before Friday night's game against the Los Angeles Angels.
Miller's arrival gives Detroit an extra option in the bullpen on a night when left-hander Drew Smyly is making his first start of the season. Smyly is going to be part of the starting rotation, but he's pitched exclusively in relief so far this year because days off have allowed the Tigers to get by without needing all five starters.
Sager to undergo treatment: TNT analyst Craig Sager will miss the NBA playoffs as he undergoes treatment for leukemia.
A sideline reporter famous for his brightly colored suits, Sager's sense of humor was intact in a statement released by Turner Sports on Friday.
Sager describes the postseason as "my favorite time of year - city to city, round by round, 40 games in 40 nights." He says that "a dramatic turn has matched me with acute myeloid leukemia. From the sidelines to being sidelined, 40 veins and 40 electrolytes."
Hood entering draft: Duke sophomore Rodney Hood is entering the NBA draft. Hood said in a statement Friday that playing for the Blue Devils and Mike Krzyzewski "helped me grow and develop as a player and a person" to prepare him for the NBA.
Renovated hall: Michigan coach Brady Hoke says there's an arms race among college football programs to have the nation's best facilities.
Hoke says you're not going to find a better one than Schembechler Hall.
Michigan gave the media a tour on Friday of the new-look building, which has been renovated for $9 million.
A life-sized statue of late, great coach Bo Schembechler is the first thing visitors see outside the entrance. Inside, there is a spectacular display of the program's history in the Towsley Museum.
There are multi-media interactive features, including one that highlights Michigan Football Legends such as Desmond Howard and Tom Harmon.
