Arenado, De Los Santos earn AFL honors

Third baseman batted .429 while pitcher fanned 13

PHOENIX -- Salt River third baseman Nolan Arenado (COL) and Surprise left-handed starting pitcher Miguel De Los Santos (TEX) are the Arizona Fall League's week four Player and Pitcher of the Week, respectively.

Player of the Week
The 20-year-old Arenado hit .429 (9-for-21) last week with 3 doubles, 3 home runs, 5 RBI and 4 runs.

Among league leaders in most offensive categories, the Newport Beach, Calif. native leads the Fall League in RBIs (24) and is tied for the lead in extra-base hits (11), ranks second in hits (29), batting (.392) and total bases (50), third in slugging percentage (.767) and is tied for fourth in home runs (five). He has hit safely in 16 of his 17 appearances with at least one RBI in 13 of those games.

The 6-1, 205-pounder was the Rockies' second-round (59th overall) selection in the 2009 Draft. He spent 2011 at Class A Advanced Modesto where he hit .298 with 20 home runs and led the Minor Leagues with 122 RBIs.

He is a .302 hitter over three Minor League seasons with 34 home runs and 209 RBIs.

Pitcher of the Week
The 23-year-old lefty from La Romana, Dominican Republic was 2-0 in as many starts last week with a 3.00 ERA while allowing only six hits and two walks with 13 strikeouts over nine innings.

Last Saturday, he started and pitched the first five innings of the Arizona Fall League's first one-hit shutout since 2007, combining with four relievers to accomplish the rarity. De Los Santos recorded eight strikeouts in the game, which shares the Fall League single-game high this season.

The 6-foot-1, 205-pounder had 20 outings in 2011 between Class A Advanced Myrtle Beach (13 games), Double-A Frisco (6 games) and the rookie-level Arizona League (1 game), combining for a 7-6 record. Over six Minor League seasons, he is 12-13 with a 3.58 ERA and 434 strikeouts in 274 innings.
