LEXINGTON, Ky. (AP) Tyler Herro couldn't miss in the second half, and he didn't have much margin for error as he helped bail out No. 4 Kentucky Wildcats against Arkansas Razorbacks.

Herro had career highs of five 3-pointers and 29 points, including two free throws with five seconds remaining, and Kentucky rallied from a 15-point deficit to beat Arkansas 70-66 on Tuesday night.

Out of sorts for 22 minutes, the Wildcats (24-4, 13-2 Southeastern Conference) quickly regrouped behind Herro, who finished 5 of 6 from behind the arc and 9 of 10 overall. His long-range baskets 43 seconds apart sparked an 18-3 run over 7:43, and the freshman guard capped the spurt with another 3 for a 54-51 lead.

Herro made all five attempts after halftime and all six shots from the foul line to top his previous high of 24 points against rival Louisville in December.

''The shots were just falling tonight,'' Herro said.

Arkansas (14-14, 5-10) stayed within a couple of possessions over the final seven minutes but couldn't break through. Kentucky got clutch free throws in the last 26 seconds from PJ Washington, Herro and Hagans, who made two with 1.3 seconds left to seal the Wildcats' fourth consecutive victory.

Kentucky's seventh straight series win over Arkansas also helped it maintain a share of the SEC lead.

Keldon Johnson added 13 points, and Nick Richards came off the bench to grab 15 rebounds for the Wildcats, who shot 50 percent from the field. The Wildcats made 12 of 22 after the break (55 percent) and converted 15 of 20 from the foul line.

''We couldn't really hit anything in the first half and they were hitting everything,'' Johnson said. ''But we just knew we had to stay together and we'd be fine.''

Isaiah Joe had five 3s for 19 points and Desi Sills 15 for the Razorbacks, who shot 31 percent in the second half and lost their sixth in a row.

''I thought we kind of panicked a bit,'' Arkansas coach Mike Anderson said. ''But Kentucky's a great team and you know they're going to make a run. ... It was a fight to the end.''

ON A ROLL

Herro's night at the line extended his run of perfect games to 11 of the last 16 and has made 46 of 47 over that stretch. He was 8 of 9 in a win against then-No. 1 Tennessee two weeks ago.

''I feel like it's going to go in every time I shoot a free throw,'' said Herro, who has made 69 of 74 (93 percent) this season.

CORRECTING MISTAKES

Kentucky improved from committing 12 turnovers in the first half to making just three in the second. Arkansas had six after the break after committing just one in the first 20 minutes.

POLL IMPLICATIONS

Kentucky answered a wake-up call to maintain its top-five standing with a bigger challenge looming this weekend at No. 7 Tennessee.

BIG PICTURE

Arkansas: The Razorbacks had the pace and momentum they wanted but couldn't sustain either in ending the month 2-6. Everything that worked in the first half fell apart in the second as Arkansas fell to .500 on the season.

Kentucky: The late-evening start might have contributed to their sluggishness, but the Wildcats found a way out of it to win the tuneup for the showdown at Tennessee. Richards' rebounding provided a 40-27 edge, and his inside presence was key in shutting down the Hogs. That led to chances for Herro that paid off with 17 points after the break.

''We got more aggressive, we got our intensity, our fight jumped up,'' coach John Calipari said. ''Good rebounding and some other stuff.''

UP NEXT

Arkansas hosts Mississippi on Saturday, seeking to avenge an 84-67 loss on Jan. 19.

Kentucky visits No. 7 Tennessee on Saturday in the rematch between conference co-leaders. The Wildcats won the previous meeting 86-69 on Feb. 16.
