Matt Mercer has become used to baseball scouts pointing radar guns at him.

"I can block it out," the Oregon right-handed pitcher said. "I have been throwing in front of scouts since high school so nobody can put as much pressure on me as I do or have higher standards for myself than I do."

The 6-foot-1, 185-pounder was not drafted out of Timberline High School in Lacey, Wash., following his senior season in 2015, but could go in the early rounds of the Major League Baseball draft that runs Monday through Wednesday. He is ranked as the No. 105 prospect by MLB.com.

Mercer is likely to leave Oregon following his junior season when he earned honorable mention, all-Pac-12 honors by going 5-7 with a 4.16 ERA in 15 starts. He acknowledged last month before his final start at PK Park that it could be his last appearance as a Duck.

"I kind of take every start as possibly my last one," he said. "I've gotten through injuries, I've had Tommy John surgery, and had to experience maybe having my last start already. That injury took me a while to come back from. I'm not sure how the draft will work out, but it has been a great three years and I am grateful for my opportunity here."

Mercer struck out 86 in 88 2/3 innings this season to rank eighth in UO single-season history. He ranks fifth in career starts with 35 and ninth with 178 strikeouts in three seasons.

Oregon also will likely have juniors Jakob Goldfarb and Parker Kelly selected in the draft.

Goldfarb was an honorable mention all-conference pick when he led the team with a .308 batting average and 35 runs scored while tying for top marks with 13 doubles and six homers. The right fielder set a school record with 12 outfield assists in three seasons, including seven last year.

"I have had some scouts reach out to ask if I had an advisor," said Goldfarb, who sat out a redshirt season in 2017 due to injury and earned his degree from the school. "They asked if I started to think about pro ball and where my head is at."

Kelly was drafted in the 34th round out of high school by St. Louis before sticking with his commitment to the Ducks. He went 4-0 with a 3.26 ERA and three saves out of the bullpen as a junior.

Senior second baseman Kyle Kasser, who hit .278 to earn all-conference honorable mention, could also be selected.

The Ducks might also lose some recruits including Vinny Tosti, an outfielder from Mater Dei High School in Santa Ana, Calif.

Former Oregon pitcher Isaiah Carranza is ranked as the No. 166 prospect in the draft after going 9-1 with a 3.89 ERA as a junior in his first season after transferring to Azusa Pacific.

Oregon State will have a host of players selected including second baseman Nick Madrigal, who is likely to be taken among the first five picks and become the highest-drafted player ever for the Beavers.

Outfielder Trevor Larnach, ranked No. 26 by MLB.com, could also be a first-round pick while shortstop Cadyn Grenier is listed at No. 68 on that ranking.

Pac-12 pitcher of the year Luke Heimlich will again wait to see if he is drafted following the revelation last year that he pleaded guilty to molesting a 6-year-old girl. Heimlich was projected to be taken among the Top 100 players last year, but went undrafted and his draft status has once again been a topic of discussion this season.

Pitcher Bryce Fehmel, third baseman Michael Gretler, first baseman Zak Taylor and outfielder Steven Kwan are also expected to be picked from OSU. In addition, sophomore closer Jake Mulholland is eligible to be drafted because he turned 21 in March.
