With college football making its annual return and the baseball postseason approaching, there's an autumn feeling to our search for this week's Greatest Athlete on Earth.

Drew Lock set school records when he scored seven touchdowns and threw for 521 yards against Missouri State in Week 1 of the college football season. The Missouri QB was named Walter Camp Player of the Week following his stellar performance on the gridiron.

Orioles' Welington Castillo might be one of the hottest hitters in the league over the last week, batting .491 with five homers, as he tries to keep Baltimore's AL Wild Card chances alive with a month left in the regular season.

Costa Rican soccer player Marco Urena scored two goals for the national team against the USMNT on Friday. The Ticos were projected to lose the World Cup qualifier but pulled away with a 2-0 victory.

And now on to our top five …

5. Joe Canning

Canning scored 10 points for Galway in the All-Ireland Senior Hurling Championship, as his team claimed the crown with a final score of 26-23 on Sunday over Waterford. It was Galway's first title since 1988.

4. Robbie Ray

The bearded young ace continued to dominate over his past two starts, both against the division-leading Dodgers: Ray threw 6 2/3 innings of four-hit, one-run ball with 10 strikeouts on Aug. 30 and followed up that performance with 7 2/3 shutout innings and 14 strikeouts in his stellar Labor Day start.

3. Josh Rosen

UCLA's Rosen led the charge in the Labor Day season opener against Texas A&M. The Bruins overcame a 34-point deficit to notch a 45-44 victory, and Rosen finished the nail-biting contest with 491 passing yards and four touchdowns.

2. J.D. Martinez

Martinez propelled the D-backs to their 11th straight victory on Monday by crushing four longballs -- each off a different pitcher. The outfielder is only the 18th player to slug four homers in a game in MLB history, and the first in D-backs history.

1. J.J. Watt

Following the devastating hurricane that hit the Houston area last week, Texans defensive end J.J. Watt established the Houston Flood Relief Fund and set out to raise $200,000. As of Monday, Watt surpassed his goal, amassing an incredible $18.5 million and thanked the donors on Twitter.
