NEW YORK (Ticker) -- Arizona Diamondbacks lefthander Randy Johnson, who was 2-0 with a 1.06 ERA, and Chicago Cubs right fielder Sammy Sosa, who batted .560 (14-for-25) with six home runs and 19 RBI, Monday were named National League co-Players of the Week.

Johnson struck out 25 in 17 innings, including 14 as the Diamondbacks routed the Florida Marlins on Saturday. He also tossed a two-hit shutout last Monday at the New York Mets.

"The Big Unit" moved past Hall of Famer Tom Seaver into fifth place on the all-time strikeout list. Johnson fanned five of the first six batters in the Florida game and when he struck out Preston Wilson in the second inning, moved past Seaver, who had 3,640 career strikeouts. The three-time defending NL Cy Young Award winner finished with 3,652.

Sosa on Saturday became the fifth player in history to homer in three consecutive innings, when he launched three-run blasts in the third, fourth and fifth innings of the Cubs' victory at Colorado.

He also matched Johnny Mize's major league mark with his sixth career three-homer game. Sosa also tied the Cubs' record of nine RBI in a game, which was established on June 11, 1911 by Heinie Zimmerman.

On Sunday, Sosa had a grand slam and drove in five runs to set the NL record for RBI in consecutive games with 14.

In a week when San Francisco's Barry Bonds became just the fourth player to record his 600th career home run, other players nominated were Montreal's Vladimir Guerrero, Cincinnati's Aaron Boone, Los Angeles' Shawn Green, Mark Grudzielanek and Adrian Beltre and the New York Mets' Steve Trachsel.
